The V6 Plus is a professional underwater robot that can dive up to a depth of 150 meters underwater to complete a variety of photographic and video graphic tasks. It is an efficient tool for diving, fishing, boating, yachting, sailing, and other ocean activities; the V6 Plus can also be used as professional detection equipment for aquaculture industry, infrastructure inspection and other underwater observation tasks.

System Overview

  • The vehicle has 2 horizontal and 4 vertical thrusters and can move underwater in all directions.
  • Degrees of motion freedom (DOF): left & right, up & down, forward & backward, Rotation: 360° pitch, 360° roll, 360° yaw
  • The vehicle is operated from the surface via umbilical cable (4.5mm) using the remote control or tablet (Bluetooth) based on video and data from compass and depth sensors
  • V6 Plus is capable of locking in any posture while moving under water
  • The ROV maximum operation depth is 150m.
  • The ROV is equipped with a 4K/1080P colour camera
  • Two ultra-bright LEDs lights (3000 lumen each) are installed at both sides of the vehicle.
  • The ROV is powered from the intelligent battery pack located inside the ROV
  • The intelligent battery pack gives a running time of 4 to 8 hours depending operations conditions
  • The complete system is packed into one plastic carry case (optional), it contains the underwater vehicle, tether deployment system, intelligent battery pack, battery charger and remote controller
  • The size of operating area is limited the cable length, which is 300 meters
  • Maximum 8m visibility can be reached during the night in clear water
  • The FiFish V6 Plus has been designed and manufactured using high quality components to withstand harsh environments.
  • The small size of this system allows a single person to carry it to any remote launch site.
  • It can be easily deployed on small opportunistic platforms, including kayaks, canoes, and other small vessels.
  • The entire package is very compact and less than 13.5 kg, so checking it through the airport is easy.

Affordable Multi-Task Underwater Drone

Many of the tasks assigned to work class ROVs – or human divers – is shallow (less than 300m) and involves searching, inspecting, or surveying underwater. These tasks are ideally suited to FiFish V6 Plus mini ROV technology. Smaller, lighter, ROVs that consume very little power can be deployed from many different areas or rigs and ships. Since they have very little mass, they can be safely used on comparatively delicate machinery without fear of damage.
Launching simply involves heaving the submersible by hand into the water. They can be deployed in sea states that would be too dangerous for larger machines. Their thrust to weight ratio for a small tether means that mini ROVs can be handle more current than most work class ROVs in shallow waters.

Exquisite and User-Friendly Design

FiFish V6 Plus is one of the smallest ROV in the market, with dimensions about 383x331x143mm. It’s easily to take everywhere in backpack or suitcase. The operate system is quite user-friendly, could easily be operated through remote control or APP.
Always ready for immediate deployment, the FiFish V6 Plus underwater robot is portable, quick and easy to launch and intuitively piloted

4K Camera & 720P Real-Time Transmission

FiFish V6 can take 4K picture and video by build-in camera and 720P real-time transmission through cable

Bionics Appearance Design

Streamlined design, gill-shaped drainage, small resistance, fast speed, good stability!

New 6 Thrusters' Layout + AI Intelligent Control Algorithm

V6 Plus’s thrusters deliver you 6 degrees of freedom, allowing mobility in all directions as well as rotations in 360° rolls, pans & tilts. The Posture LockTM secures the angle of your drone as you move in any direction.
The vertical propellers are layouted as a rectangle, which is combined with AI intelligent control algorithm to ensure the stability of the ROV in both vertical and horizontal directions under water.
The rear two propellers output a maximum speed of 3.2 knots (1.6m/s) and flow resistance.

Unlimited angles for underwater photography

Unlimited angles for underwater photography, and capable to produce the creative and revolutionary underwater footage Moves laterally, forward & backward, up & down, as well as roll, pan and tilt. The player can also combine different movements, such as arc, nose dive, spiral etc.

AR Scaler

Underwater Lasers are intended to be used by ROVs (Remote Operate Vehicles) using video images to take general measurements. By paralleling two laser beams that are calibrated for set distances, accurate measurements from video images are possible.
AR Scaler includes: AR scaler—based on machine vision, Laser ruler—based on traditional laser measurement
QYSEA patent AR scaler's precision is up to 1cm. Self-adaptive measurement and visualized data are visible on FIFISH APP. By moving the scaler and customizing color of scaler, with one simple click you can save the measuring result.

VR Head Tracking

Customized Remote Control and VR Goggle Offers 3 Kinds of Flexible and Intelligent Control Modes
Integrating VR smart technology that fully immerses the user into the underwater world, the Head Tracking feature lets you yourself into the drone’s first-person-view and control where you want to go simply by turning your head.

One Touch Lock-Depth Mode

The Depth-Lock Mode can be One-Touch set on controller, ROV can hover in the water or stay in the depth to navigate.

Small, Portable and Easy To Travel

MacBook Pro size, a backpack can fit the whole set of equipment, making your travel more convenient.


It has underwater filters and multiple soundtracks to help you edit the film like pro.
Editing, Soundtrack, Color restoration, Instant Sharing

Sonar Distance Lock System

The embedded sonar system features a distance-measuring function. In addition, DL (Distance Lock) enables the V6 plus to fix it’s height and speed, reducing the operational complexity and allowing the pilot to better focus on capturing and recording important images. This makes V6 Plus the ideal ROV for inspections of all kinds (i.e., large vessel, boat / yacht, bridge inspection, infrastructure, etc).

Quickly data transfer and store

The SD card is removable, and all data is instantly exported. The SD card comes standard with 128GB, and can support up to 512GB.
